Application September 19, 1933, Serial No. 690,156

3 Claims.

My invention relates to' bottles and it consists in the combinations, constructions, and arrangements herein shown and described.

An object of my invention is to provide a bottle `which cannot be opened without giving evidence thereof so as to preclude the further commercial use of the bottle for theusame purpose. Y

A further object of the invention is to provide a device of the type described which has a screw pap, the cap, however, serving the purpose of a closure so as to seal the contents as long as th e bottle is in use.

A further object of the invention is to provide a device of the type in which a frangible locking flug is provided which when broken will permit the turning of the cap to open the bottle.

A still further object is to provide a construetion in which the locking of the cap on the bottle is easily accomplished even though the cap is screw-threaded.

Other objects and advantages will appear in the following specification and the novel features of the invention will be particularly pointed out in the appended claims.

My invention is illustrated in the accompanying drawing forming part of this application, in which:

Figure 1 is a perspective view of a bottle showing the cap in its locked position,

'j Figure 2 is an enlarged sectional view showing the construction of the cap,

Figure 3 is a modified form of the device,

Figure 4 is a perspective view of a portion of another modiiied form, and Figure 5 is a sectional View of a portion of the form shown in Figure 4.

In carrying out my invention I make use of a bottle of any suitable shape such as that shown at 1 in Figs. 1 and 2. It will be observed that this `bottle has a iiange 2 cast integrally therewith and that it is provided with a frangible lug 3 extending outwardly from the flange. The bottle neck is threaded, as shown at 4. This threaded portion receives an inner metal cap 5 which can be screwed on the neck until the cap becomes tight "on the top of the bottle. The cap may have a cork filler 6 and a sealing disc 'l which bears on the top of the bottle.

It will be understood, of course, that the bottle is filled with the liquid to be sold prior to the application of the metal cap. When the cap is in place a coating of cement 8 is applied to the exterior of the threaded cap and an outer cap portion 9 is then placed over the inner cap por- -;ti on 5 to which the cement has been applied and (Cl. 21E-7) the cement is allowed to harden. The outer cap portion has a recess 10 which ts over the lug 3 so as to allow the outer cap portion to surround the flange 2 for at least a portion of its width.

When the cement hardens it virtually forms a unitary cap structure by cementing the inner and the outer cap portions together. The bottle cannot be opened without breaking the frangible lug 3. When this lug is broken then the cap as a whole may be unscrewed to permit access to the contents of the bottle. If a small portion of the contents is to be used the cap can again be screwed on to the bottle as with an ordinary screw cap.

In Figure 3 I have shown a modified form of the outer cap member at 9a. In this form of the device the lug 3 is engaged by a tongue or iiange portion ll which prevents the turning of the screw cap as a whole but which will permit the outer cap portion 9a to be easily placed in position after the plastic cement has been applied to the inner cap.

In Figures 4 and 5, I have sho-wn afurther modified form in which an outer cap member 9b having a recess 10b which iits over a frangible lug 3d. This outer cap member is threaded interiorly and is arranged to receive a threaded 1 inner cap member 5b. When the outer cap member 9b is in place the inner cap member has cement applied thereto and then is screwed to the neck of the bottle and also to the threaded outer member 9b which is prevented from turning by the lug 3b. In this form of the device the sealing members 12 and 13 are in the cap member 5b.

As in the form shown in Figs. 1 and 2 it is only necessary to break off the lug 3b to permit the cap as a whole to be unscrewed, vthe members 9b and 5b being firmly cemented together by any suitable binding cement.

I am aware that it is not broadly new to lock bottle caps in position by frangible lugs so that I do not broadly claim such a construction.

The inner cap may be made of metal or of any suitable material.

What I claim is:

V1. The combination with a bottle having a threaded neck and a frangible lug carried thereby, of a cap comprising an inner threaded cap member, an outer cap member having a shoulder arranged to engage the lug to prevent normal rotation thereof, and an intervening layer of cement for securing the cap portions rigidly together. y

2. The combination with a bottle having a threaded neck and a frangible lug carried therethe bottle neck, an outer metal cap member having threads arranged to register with the threads of the bottle and being provided with a recess arranged to receive said frangible lug, and a layer of cement disposed between the registering threaded portions of the inner and outer cap members for securing them permanently together.
